JOHN TATE, OF MILLVALE, PENNSYLVANIA.

IMPROVEMENT IN FLUXING COMPOUNDS FOR MANUFACTURE OF IRON.

Specification forming part of Letters Patent No. 222,369, dated December 9, 1879; application filed April 18, 1879.

To all whom it may concern:

Be it known that I, JOHN TATE, of Millvale, in the county of- Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Fluxing Compounds for the Manufacture of Iron direct from the Ore; and

I do hereby declare that the following is a full I and exact description thereof.

My invention relates to an improvement in the manufacture of iron direct from the ore; and it consists of a fluxing, detersive, and converting agent composed of the following ingredients: borax, chalk, hydrate of lime, mu-

riate of soda, manganese, chlorine-water, china-clay, charcoal, fire-clay, flint-glass, and

bottle-glass, used in about the proportions I I specified, and treated in the manner, and used in a furnace with the ore, as hereinafter specified.

To enable others skilled in the art to use my invention, I will proceed to describe its use.

In the preparation of the flu-xing, detersive, and converting agent, I take of the following ingredients aboutborax, two pounds; chalk, one and one-fourth pound; hydrate of lime,

three pounds; muriate of soda, six pounds;

manganese, three pounds; china-clay, two

pounds; charcoal, eight pounds; fire-clay, ten

pounds; flint-glass, four pounds, and bottleglass, three pounds, and thoroughly mix them together, so as to form a homogeneous mass, which I mix with every one hundred pounds of powdered ore.

sufficient to moisten the ore, which isathen charged in the furnace and melted in the usual manner and by the ordinary means, I

When the ore is melted the furnace is tapped and the metal formed into pigs, which may be afterward placed in the heating-furnace agent, composed of borax, chalk, hydrate of lime, muriate of soda, manganese, chlorine- I water, china-clay, charcoal, fire-clay, flintglass, and bottle-glass, mixed with ore in 7 about the proportions specified, and the whole mass charged into the furnace, substantially as and for the purpose set forth.
